T 0 all 10710171- it may concern:

Be it known that 1, CHARLES E. SLoooMB, a citizen of the United States, residing in the city of VJilmington, county of Newcastle, tate of Delaware, have invented a new and useful Oiling- Off Machine, of which the following is a specification.

This invention relates to machines for surface coating and treating of skins, and more particularly to a machine for applying oil in what is known as the oiling oif process and has for an object to provide a machine with. a suitable mechanism for feeding the skins through the machine, and during which operation oil is applied to one side thereof and. distributed and worked into the surface of the skin.

it has for a further object to provide a means for controlling the amount of oil necessary for a particular skin or skins, and which means may be regulated and adjusted during the operation of the machine to vary the quantity of oil should it be desired and necessary so to do.

It has for a further object to provide a novel bolster mechanism for collecting the oii and then delivering it to a skin whereby an even distribution of oil is effected which has not heretofore been obtained and by which construction the oil may be thoroughly worked into the skin during the applying step.

It has for a still further object to provide a, safety mechanism for bringing the machine to rest promptly and quickly in case of danger to the operator, or for other reasons necessitating an instant releasing of the driving power.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at pres ent preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 represents a perspective of an oiling off machine embodying my invention. Fig. 2 represents a perspective of the machine taken from the rear. Fig. 3 represents a side elevation of the machine certain parts being omitted. Fig. 4 represents a detail of the driving mechanism. F ig. 5 represents an elevation of the opposite side of the machine from Fig. 41-, showing also a modified bolster construction. Fig. 6 represents a detail partly in section, of the means for maintaining the oil in proper condition for application to a skin. Fig. '7 represents a perspective of a portion of the machine showing a modified bolster construction. Fig. 8 represents a detail of the gage adjusting mechanism. Fig. 9 represents a side elevation of the same. Fig. 10 represents a detail of the gage operating bar and its adjuncts. Fig. 11 represents a detail partly in section of the oil guard.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings :-1 designates the frame of a machine embodying my invention, the same having journaled thereon in a suitable manner a shaft 2 carrying a driving pulley 3 and loose pulley i, the said pulleys being driven from any suitable source of power. Fixedly secured in the present instance to the shaft 2 is a pinion 5 meshing with a gear 6 which is carried by a countershaft 7, rotatably mounted in the frame 1 and having thereon a pinion S in mesh with a gear 9, the latter being keyed or otherwise secured to the main shaft 10 of the machine by which certain of the operating mechanism is driven.

11 designates a drum or carrier mounted for rotation with the shaft 10 and forming the support for a skin during its passage through the machine and the oil applying steps.

12 designates a trough or reservoir suit" ably mounted on the frame 1 and located at a convenient point for use in applying oil to a skin and preferably having a flexible inlet conduit 13 communicating therewith by means of which oil is supplied from a suitable pumping element 14: and having an outlet conduit 15 by which the level of the oil in the reservoir 12 is regulated. In the present instance, the reservoir 12 is adjustably mounted on the frame 1 and for this purpose is provided with depending threaded studs turn conduit 15.

* tion for use.

- a drain cock 23 for the usual purpose.

16, which are adapted to be inserted in an curethe reservoir in a determined position,-

it, of course, being apparent that this construction permits the reservoir to be raised or lowered as necessary to adjust its position relative'to the oil applying device.

19 designates an oil supply tank with which the inlet conduit 20 of the pumping element 14 communicates as does also the re I In this tank 19, I preferably locate a heating coil. 21 adaptedto be supplied with a heating medium from any suitable source and by means of which the oil is maintained in a proper viscous condi- It will of course be understood that the tank 19 is provided with a lid 22 preferably hinged thereto to-allow the oil to be placed in the tank and there is also In connection with the heating of the oil, it

will be noted that a coil 24 is preferably pro vided within the reservoir 12 and supplied with a suitable heating medium for the pur pose of maintaining the oil in the required J state.

25 designates a dipping roll rotatably carframe 1 whereby the bolster 27 or oil applying device is guided into and through the oil in the reservoir 12, it being noted that the latter is so adjusted as to bring a portion of the circumference of theroll 25 into the Oli. The bolster 27 is supported and guided by suitable rolls 28 passing about the dipping roll 25, from which it passes to a pressure roll 29 operatively mounted adjacent thereto andpositioned to deliver the bolster to the applying roll 30. This latter roll is rotatably mounted on the frame 1 and carries a gear 31 which transmits its motion to a similar gear 32 of the pressure roll 29, and its motion is also conveyed by chain 33 and sprockets 3-1 and 35, to the driving mechanism 36 of the pumping element 1 1. From the applying roll 30 the bolster passes over a guide roll 37 and then under a positioning roll 38 located in close proximity to the surface of the drum 11 and adjacent one side of a brush roll '39. In. connection with the roll 38 it will be noted that there are a plurality of these rolls similarly disposed with respect to the drumll and located on each side of the brush rolls 39 and 40, there being inthe present instance two of these brush rolls suitably located with respect to each other and in position to engage the surface of a skin as it passes over the drum 11. The bolster after passing under the brush roll 39 and the second positioning roll 33 again passes over a guide roll ll in order to properation of the said brush roll 39 and attention is here directed to the fact that the roll will be understood.

41 is positioned and located farther from the drum 11 than the guide roll 37, the function of which will hereinafter be brought out. Leaving the guide roll 41, the bolster passes beneath another positioning roll, 38, then between the drum 11 and the brush roll 10, beneath the positioning roll 38 thereof, and then over another guide roll 12, which is preferably mounted farther from the surface of the drum than the guide roll 41. From this latter roll the bolster passes around the first of the guide or return rolls 28, directing it back to the starting point.

. The skin is next delivered to a wiper roll 13 sultably mounted for rotatlon 1n the frame 1 and having the brush surface thereof normally positioned to contact and bear against the skin as it passes over the drum 11. The

function of this brush roll 43 is to give a final wiping or distributing of the oil which has previously been applied and worked into the skin.

.tl designates a bevel gear. suitably keyed to the main shaft 10 and having in mesh therewith a plurality of similar gears 4L5 each of which is mounted on a spindle 4e" suitably journaled in the frame structure 1. 17 designates respectivelybevel gears in the present instance fixedly secured to ceritain of the spindles 46 and meshing with gears 18 and a9, carried respectively by the shaft of one of the guide rolls 28 and the shaft of the applying roll 30, whereby these rolls are driven to transmit movement to the bolster 27 and other ad uncts.

5O designates a bevel gear in mesh with each of the similar gears51 carried by the shafts 52 of the brush rolls 39 and 40. These gears are each preferably slidably mounted on the spindles 4:6 and rotate therewith through the medium of keys or splines 53 as Bearing brackets 54: are provided for the gears 50 and secured to the frame 1 by bolts 55 or the like passing through suitable slots 56 whereby the j position of the said gears 50 may be varied to correspond to any change in position of the brush rolls 39 and 10, it being understood that it is desirable to mount said rolls for adjustment relative to the drum 11. shown, by threaded studs 57 preferably fixed to'the frame 1 and passing through lugs 58 of the brush journals 59, a nut 60- ;being interposed between the said lugs to iefiect the necessary movement. imanner the position of the brush rolls 39 jand 40 maybe varied relative to the drum @11, whereby skins of different thickness can pass through the machine, it of course benecessary to set the machine but once for a particular grade or thickness of skin. erly stretch the skin during theworking op- In this 61 designates a pulley keyed to the shaft This adjustment is effected, as here shaft 2, and it will here be noted that the journals 59 of the shaft 62 are mounted for adjustment in a manner similar to the means described in connection with the brush rolls 39 and 40, and the parts have therefore been correspondingly provided with reference numerals and repetition of the description is deemed unnecessary' 65 designates an oil guard partially inclosing the wiper roll 43 and having an outlet conduit 66 secured to and communicating therewith, by means of which the superfluous oil is conducted to a trough or well 67, preferably located beneath the drum 11 and in position to receive the oil drip from the said drum. This well 67 is provided with an outlet 68 or drain by which the oil collected may be Withdrawn when necessary.

69 designates a table upon which the skins are placed preparatory to entering the machine and from which they are delivered to the drum 11 first passing beneath a guard roll 70, suitably mounted adjacent the drum 11 and serving as a means to prevent the hands of the operator being caught by the more powerful oil applying roll 30. In connection with the applying of oil to the bolster 27, attention is here directed to the mounting of the pressure roll 29, since the shaft 71 thereof carrying the gear 32 is mounted in bearings 7 2 adapted for sliding movement relative to the frame 1, and which are normally maintained in position by means of threaded rods 7 3, each of which passes through a guide bracket 74 forming an abutment for a spring 75 outwardly pressing against a nut 76 of the said rods 73. This construction affords a means of regulating the quantity of oil which is to be applied to the skin by the bolster. Normally and initially, the position of the pressure roll 29 is adjusted by the spring 7 5 and the nut 7 6 to supply as near as possible the correct quantity of oil, but should it be found, while the machine is in operation,

that too much or too little oil is being carried to the skins, the pressure roll 29 may be adjusted by the mechanism now to be described.

77 designates a bell crank suitably pivoted at 7 8 to the frame 1 and preferably having a bifurcated end 79 adapted to straddle the stud 73 and seat against a nut 80 or the like threaded thereon. As here shown, there is one bell crank 77 for each stud 7 3 whereby the bearings 72 may move in unison and thus cause the position of the pressure roll 29 to vary relative to the roll 30, thus allowing more or less oil to be absorbed or carried by the bolster 27 for application to the skin. Each of the bell cranks in the pres ent instance is connected to a rod 81 having connection with a pivoted bell crank 82, the latter having a rod 83 secured to a pin 8-1 mounted on a disk 85 or the like. It will be notedthat the pins 84: for the rods 83 are preferably oppositely disposed on either side of the disk 85, whereby movement of the said disk causes the bell cranks 77 to move together and shift the roll 29 so that its distance from the roll 25 is varied at will and more or less of a squeezing action is exerted upon the bolster thereby controlling the quantity of oil taken up and delivered to a skin. The disk, 85, in the present instance, is movably mounted on a pivot 86 of a bracket 87 and is adapted to oscillate with respect thereto, which movement as here shown is effected by means of arms 88 secured to and projecting from the disk 85 and adapted to be manually operated. It is preferable to position the arms 88 in proximity to the knees of the operator, as thereby the mechanism controlled by them can be operated without dividing the operators attention from feeding the skins into the machine, though, of course, it will be evident they may be positioned at any suitable point to effect the desired end,

89 designates a scraper adjustably mounted on the main frame 1 and normally positioned in contact relation to the drum 11, whereby superfluous oil may be removed from the surface thereof before another skin is fed into the machine. As here shown, the scraper 89 is mounted on threaded spindles 90 having threaded engagement with a bar 91 secured to the frame 1 and the position of the scraper may be varied at the will of the operator by turning the hand wheels 92, provided for the purpose. In connection with the scraper 89, it will be noted that the same is preferably located above the tank 67 so that the latter will catch the fluid or oil removed from the surface of the drum 11. In order to take up the slack of the bolster 27, and maintain the same sufficiently tight for correct operation, one of the idle pulleys 28 is provided with bearings 93, which are slidably mounted on a portion of the frame 1 and are operated by threaded members 94:, controlled by the movement of the h and wheels 95, all of which will be perfectly clear to those skilled in the art since this adjustment is a well known mechanical movement. The bolster 27 is preferably formed of any well known material capable of carrying or absorbing an oil, but I have shown in Figs. 5 and 7 a modified form of bolster, which I consider broadly new and comprising features not heretofore attained. This modification comprises a perforated or not construction of suitable texture for the purpose intended, and by which the oil may be more uniformly distributed over the surface of the skin. It is in connection with this net type of bolster that the guide rolls 37, 1-1 and 12 are spaced at varying distances from the drum 11, since thereby the meshes of the bolster are staggered with respect to the skin after each point of contact therewith. That is to say, after the bolster 27 has contacted with the skin, and applied oil thereto at several points across the skin, the next time the bolster comes into contact with the skin its position will have been altered by the guide roll 37 and, consequently, a previously unoiled portion of the skin will be brought into contact with'the bolster, and

this operation continues for each point of contact until the skin has been uniformlymovement, thereby forming a backer of oil,

absorbing material which aids materially in applying the oil to the bolster.

97 designates an operating lever adapted to control the belt shifting mechanism, and in connection with which I preferably provide an auxiliary shifting means whereby the machine may be disconnected from the driving means when the operator is not within reach of the lever 97, and whereby the operator need not change position to bring the machine to a stop. This mechanism comprises, in the present instance, a bar 98 suitably connected at one end to the belt shifting mechanism and carrying at the opposite end a cam roller 99, it of course being und rstood that suitable bearings 100 are provided in which the bar 98 may have the required sliding movement. The roller 99 as here shown, is actuated by a side face cam 101 fixedly secured upon a rock shaft 102 so that it moves therewith and is connected by the links 103 to the arms 1041, which are pivotally mounted at 105 to the frame 1 and support thereon a foot treadle 106, preferably positioned on the operators side of the machine and in such a position that it may be engaged when it is required to stop the machine quickly. at counterweight 107 is provided to return the cam 101 to normal position after it has been shifted by a movement of the foot treadle. As soon as the foot treadle 100 is depressed,- the cam member 101 is raised into engagement with the roller 99 thereby shifting the bar 98 and moving the belt from the driving pulley to the loose pulley. i

In the operation of the machine the reser voir 12 is filled to the required level with the oil or coating fluid which is to be used, and the heating coils 21 and 2st supplied with a heating medium in order to maintain the oil of oil conveyed bysaid bolster.

in a proper state of viscosity. Power is now supplied to the machine by shifting the lever .97 and thereby the drum 11 and its adjuncts applying member 30, it of course being understood that the tension roll 29 has been previously adjusted to regulate the amount of oil carried by the bolster to the skin. The skin is conveyed by the drum 11 bene'ath'the several brush rolls 39 and 40, and wiper roll 43 from which it is delivered to an operator at this point. During the passage of the skin through the machine, it receives several coats of oil from the bolster depending upon the number of times it contacts with the bolster, and the action of the brush rolls 39 and 10 is to tho-roughly spread, distribute and work the oil into the surface of the skin. The arrangement of the guide rolls 38 is such as to .maintain theskin at all times in close contact with the drum 11, thereby preventing the edges of the skin from kicklng up or turning over, an act1on which is extremely disadvantageous in that it allows oil to be deposited upon the wrong side of the skin, :all of which 1s obviated by the use of the adapted for the purpose intended, and by means of which a large number of skins may be quickly passed through the machlne, oiled on one side and delivered ready for the next step in the process. It will now be apparent that I have devised a novel and useful constructi on of an oiling 01f machine, which em- ;bodies the features of advantage enumerated as desirable 1n the statement of the invention and the above descriptiomand while I have, in the present lnstance, shown and de scribed a preferred embodiment thereof which has been found in practice to give 'satlsfactory and rehable results, 1t 1s to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the in- ,vention or sacrificing any if its advantages.

Having thus described my invention, what I claim as new and desire to secure by Let- :ters Patent, is
